Question

The gravitational force between two asteroids is 1,000,000 n. what will the force be if the distance between the asteroids is doubled?

Answer 1

To solve this problem, we use the formula:

F = G m1 m2 / r^2

where F is gravitational force, G is constant, m1 and m2 are masses while r is the distance between the two asteroids

Since G m1 m2 is constant, therefore:

F1 r1^2 = F2 r2^2

So if r2 = 2 r1:

(1,000,000 N) (r1^2) = F2 * (2 r1)^2

F2 = 250,000 N

It was divided by 4
